An oxide /ˈɒksaɪd/ is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. Metal oxides typically contain an anion of oxygen in the oxidation state of −2. Most of the Earth's crust consists of solid oxides, the result of elements being oxidized by the oxygen in air or in water. Hydrocarbon combustion affords the two principal carbon oxides: carbon monoxide and carbon dioxide. Even materials considered pure elements often develop an oxide coating. For example, aluminium foil develops a thin skin of Al2O3 (called a passivation layer) that protects the foil from further corrosion. Different oxides of the same element are distinguished by Roman numerals denoting their oxidation number, e.g. iron(II) oxide versus iron(III) oxide. The two most common oxides in nature are silicon dioxide and water.
Due to its electronegativity, oxygen forms stable chemical bonds with almost all elements to give the corresponding oxides. Noble metals (such as gold or platinum) are prized because they resist direct chemical combination with oxygen, and substances like gold(III) oxide must be generated by indirect routes.
Mmm yeah Au Au Au August yeahh ohh
Hearts been broken, Struggling just to find a brand new start
The darkness is closing in, making everyone of my decisions hard
You've been calling, telling me you'd always be there
But it just wouldn't have been fair, to you
And they said that after the storm it'd be bright
That the clouds would give way to the sun
And I know you've been waiting for me to come around
I just needed some time to figure it all out
I was lost, there was no way that I could be what you want
And no way that I could give you my all
My heart wasn't proper, but that didn't stop ya from waiting
Til after, after, after the rain
I had to re-pair, leave behind the pieces and re-build again
Ohh, and yeah I saw you there but there's no way that I could just pretend
That I was alright and okay
I wasn't all good and I had to delay
I needed the water to wash that away
And they said that after the storm it'd be bright
That the clouds would give way to the sun
And I know you've been waiting for me to come around
I just needed some time to figure it out
Cause I was so lost there was no way that I could be what you want
And no way that I could give you my all
My heart wasn't proper, but that didn't stop ya from waiting
Til after, after, after the rain
Let it wash away all my mistakes
Cause I got so many changes to make
See from hating to loving I got to make the adjustment
From the darkness into the rising sun yeah
I'm so sorry to keep you waiting
Almost drowned cause it wouldn't stop raining
Now that all that is gone, I'm ready to carry on
I was lost, there was no way that I could be what you want
And no way that I could give you my all
My heart wasn't proper, but that didn't stop ya from waiting
Til after, after, after the rain
After the rain
Ooh, said after the rain
